Can't access region server port because it's random and unmapped

[aclowkey]

Hi,

I'm encountering an issue where my client application can't connect to the region server. It seems that the region server port is always different. I tried mapping the region server port, but it restarts the container and gets a new port.

Is there a workaround to this?

My stacktrace:
